There is following shortcoming in above-mentioned patent: one, because by same screen that institute is wired to common shielding, thereby when signal transmits, be difficult to avoid interference and decay, communication efficiency influenced; Its two, when the cable of attempting to use this patent structure was made form of springs, bendability and rebound performance were poor, influence useful life, thus to environment for use or claim that occasion has fastidious property; Its three because sheath (patent claims oversheath) adopts the low-smoke and flame retardant polyvinyl chloride, so the resistance to low temperature shortcoming, the low temperature about ability-40 ℃ only.
In view of above-mentioned prior art, be necessary to be improved, for this reason, the applicant has done useful design, and technical scheme described below produces under this background
Summary of the invention
Task of the present invention is to provide a kind of and helps to promote anti-interference and reduce to decay and use and ensure communication efficiency, be conducive to embody good bendability and rebound performance and use and increase the service life and to the wide adaptability of environment for use be of value to the 3G data communication cable that improves low temperature resistant degree.
Task of the present invention is finished like this, a kind of 3G data communication cable, comprise cable core and be positioned at the outer restrictive coating of cable core, described cable core comprises that at least two first lines are right, at least two second lines to a separator, be characterised in that described first line is to by a pair of first conductor that is coated with first insulating barrier separately, first, the second strand covering and first screen constitute, described a pair of first conductor that is coated with first insulating barrier separately is stranded each other, and wrapped first lapping layer when the first line strand, described second lapping layer is wrapped outside first lapping layer, and described first screen is positioned at outside second lapping layer; Described second line is to being made of a pair of second conductor and the secondary shielding layer that is coated with second insulating barrier separately, a pair of second conductor that is coated with second insulating barrier separately is stranded each other, and the twisting pitch of the twisting pitch of a pair of second conductor and described a pair of first conductor is inequality, second line to two-phase neighbour's first line between, the secondary shielding layer is positioned at outside second conductor, described separator is positioned at first, second line is external, wherein: described first conductor is closed by a copper foil wire and complex root tinned copper wire or complex root soft copper skein silk and constitutes, described second conductor is closed by a copper foil wire and complex root tinned copper wire or complex root soft copper skein silk equally and constitutes, and described restrictive coating is thermoplastic urethane layers.
In a specific embodiment of the present invention, described cable core also includes a ground wire and is used for making at least one gasket for packing of cable core roundingization, and ground wire and gasket for packing all are positioned at described separator.
In another specific embodiment of the present invention, the diameter of described copper foil wire is 0.23-0.27 ㎜, and the diameter of described tinned copper wire and soft copper silk is 0.077-0.083 ㎜.
In another specific embodiment of the present invention, first, second lapping layer is foaming PP twining package tape, and width is 8-16 ㎜, and thickness is 0.1-0.15 ㎜, described first screen is aluminium foil, and the width of aluminium foil is 10-18 ㎜, and thickness is 0.03-0.05 ㎜.
In another specific embodiment of the present invention, described secondary shielding layer is aluminium foil, and width is 10-18 ㎜, and thickness is 0.03-0.05 ㎜.
Also have in the specific embodiment of the present invention, described first insulating barrier is the PE insulating barrier, and described second insulating barrier is the PP insulating barrier.
More of the present invention and in specific embodiment, described separator is barrier paper, and width is 15-25 ㎜, and thickness is 0.03-0.05 ㎜.
In of the present invention and then specific embodiment, described ground wire is that 15-25 ㎜ thickness is that the barrier paper of 0.03-0.05 ㎜ constitutes for being that naked copper paper tinsel skein silk that 40 tinned copper wires of 0.077-0.083 ㎜ or soft copper silk and diameter are 0.23-0.27 ㎜ merges and be surrounded with width by diameter.
Of the present invention again more and in specific embodiment, described gasket for packing is cotton yarn.
Technical scheme provided by the invention since to first line to independently being provided with first, second lapping layer and first screen, thereby can guarantee that signal effectively reduce signal in the transmission and disturb and decay; Because the twisting pitch that first, second line is right differs from one another, and with second line to be arranged at two adjacent first lines between, thereby can reduce cross-talk and ensure communication efficiency; Because first conductor that first line is right and the second right conductor of second line have respectively used by the mutually stranded structure of a copper foil wire and complex root tinned copper wire or soft copper silk and the thermoplastic polyurethane that restrictive coating has been used to have the elastic effect of standing out from one's fellows, therefore have stronger detour song and rebound performance, not only helped to prolong the useful life of cable but also be conducive to improve adaptability to the cable use occasion, can the coiling form of springs; Restrictive coating has the technique effect of low temperature resistant reaching-55 ℃.
